Let us now calculate the self-weight or dead load of the RCC footing as shown in the drawing.
Given data:
Length at the base = L = 750mm.
Breadth at the base = B = 600mm.
Total height H = 500 mm.
Top surface length = l = 450mm.
Top surface width = b = 300mm.
Calculation:
The self-weight of any RCC structure is calculated by the formula
= [Unit weight × volume.]
As you know, the unit weight of the RCC structure = D =2500kg/cum.
The volume of the RCC footing is calculated in a separate article as linked below.

The self-weight of RCC footing
= [ 2500 kg/m³ × 0.1904m³]
= 476kg.
Let us now calculate the self-weight or dead load of the plinth beam as shown in the drawing.
Given data:
The span of the plinth beam-1 (PB1) = 4500mm.=4.5m.
The span of plinth beam-2 (PB2) = 3000mm.=3.0m.
Sectional dimension of plinth beams = 230mm. × 450mm.
= 0.23m. × 0.45m.
Calculation:
The self-weight of the PB2
= [Unit weight × (volume)]
= [ 2500 kg/m³ × (3m × 0.23m. × 0.45m.)]
= 776.25kg.
The self-weight of the PB1
= [Unit weight × (volume)]
= [ 2500 kg/m³ × (4.5m × 0.23m. × 0.45m.)]
= 1164.38kg.
